The discipline of gastroenterology involves studying the function of various organs in the GI (gastrointestinal) system, such as the stomach, intestines, pancreas, and liver. Gastroenterologists are doctors who specialize in gastroenterology. They can treat most diseases associated with these organs, from simple digestion issues to complex conditions like hepatitis C and liver disease. Here is a simple overview of what these professionals do, their qualifications, their charges, and how to find them.

What does a gastroenterologist do?
Individuals usually visit a primary physician when they experience abdominal pain, difficulty swallowing, blood in the stool, and digestive problems like persistent constipation, diarrhea, acid reflux, or indigestion. If the primary physician performs an examination and finds that the problem could be severe, they recommend the patient to a gastroenterologist for an in-depth examination. It is because gastroenterologists are trained in identifying and treating severe GI diseases. In some cases, individuals may directly contact a gastroenterologist if they experience symptoms related to the stomach that are too hard to bear.

A gastroenterologist is well-equipped to perform the following procedures to diagnose and treat GI diseases:

• Upper endoscopy to inspect the upper gastrointestinal system
• Enteroscopy to examine the small intestine
• Colonoscopy to inspect the large intestine
• Endoscopic ultrasound to examine the digestive system using a tool called an endoscope
• Upper endoscopy to examine the bile ducts by capturing video X-rays (fluoroscopic X-rays)
• Polypectomy to remove the stomach or intestinal polyps

These tests give gastroenterologists a closer look at the internal organs, allowing them to determine how they are functioning and what might be causing the symptoms. The expert uses various tools to perform these procedures and evaluate the patient’s health. While they do not perform surgery, they occasionally work with GI surgeons.

What kind of education do gastroenterologists have?
Gastroenterologists are internists, which means they focus on internal healthcare. Like other doctors, they begin their training in medical school. Following that, they pursue residency and fellowship. The following are the pre-requisites to becoming a board-certified gastroenterologist:

• College and medical school degrees
• A three-year residency working alongside experienced gastroenterologists
• Around 36 months of fellowship to receive training in endoscopy
• An ABIM certification received after passing the gastroenterology specialty exam.

A gastroenterologist does not need to be board certified to practice, but it is a crucial qualification to search for. It demonstrates one’s knowledge and training in the field. Some also undertake an additional year of education in handling patients. This course provides training in fields like pediatric gastroenterology or transplant hepatology (treatment of patients who could require liver transplants).

What to expect from a visit to the gastroenterologist?
A gastroenterologist may work at a hospital or practice in a private clinic. When a person visits the healthcare facility, the expert examines them physically and inquires about their symptoms. During the physical examination, the gastroenterologist normally applies pressure on the outside of the patient’s tummy while the individual lies on a table. They then feel for anything odd, inquire about pain, and listen for strange noises.

Depending on the findings, the gastroenterologist might refer the patient for additional examinations or diagnostic treatments, like an upper endoscopy or colonoscopy. These procedures involve inserting a tiny camera into the digestive system to give the doctor a clear picture. After obtaining a diagnosis, the doctor discusses a treatment plan with the patient.

Do gastroenterologists treat cancer?
If a person has a tumor in a digestive system organ, a gastroenterologist can diagnose and remove it using surgery. The specialist may also use other procedures to determine the disease’s stage. For instance, they may conduct a biopsy where tissue samples are examined in a laboratory. People over 50 may visit the expert for routine check-ups for the early identification of colon cancer.

How much do gastroenterologist visits cost?
The cost depends on the type of test or treatment performed. While physical examinations are relatively affordable, the price can shoot up for an endoscopy or colonoscopy. The charges also depend on how challenging the problem is and the doctor’s experience level. Besides the cost of treatment, gastroenterologists may charge a consultation fee.

If patients have insurance coverage, they can request the expert for a recommendation for reimbursement. The maximum amount one can claim depends on the procedure and the type of insurance policy.

How to find a gastroenterologist?
The best way to find one is to ask the primary physician for a referral. Alternatively, one can contact a hospital, seek recommendations from friends and family, or use the internet. However, patients should research the doctor’s credentials, experience, and success rate to make an informed decision.
